PAYMENT impossible

I have tried with two different card to buy the pro version of Plugin: Ci WooCommerce Product Gallery Slider but the message is still the same:
Payment unsuccessful – there was a problem processing your credit card.
For security reasons we may need you to re-enter your Visa or MasterCard details before trying again, or you may need to try an alternative payment method.

Could you please let me know how I can proceed?

Many thanks in advance,
Kind regards
